7 Claims.

, This invention relates to air conditioning apparatus, more particularly to apparatus so constructed and arranged as to be adjustable with respect to a supporting surface, and the principal object of this invention is to provide new and improved apparatus of these types. This application is a division of my co-pending application Serial Number.150,597, filed June 26, 1937.

In the drawing accompanying this specification and forming a part of this application, there is shown, for purposes of illustration, one form which the invention may assume, and in this drawing:

Figure 1 is a vertical sectional view through an air conditioning apparatus, illustrating the embodiment of the invention,

Figure 2 is a front elevational view of the apparatus shown in Figure l, and

Figure 3 is an enlarged sectional view corresponding generally to the line 3--3 of Figure 1.

Referring particularly to Figures 1 and 2, the air conditioning apparatus I!) comprises an outer casing l5, having a front portion l2, and a rear portion 56. The front portion l2 houses an interior casing IS, in which is disposed a chamber. member 26, through which products of combustion from a burner (not shown) disposed within the member 26, are conducted to a flue pipe 6!] at the exhaust end of the member 26, and from there out through an exhaust stack 63..

The rear portion 56, of the outer casing [5, has an air inlet 51, providing for supply of air to the inlet of a blower unit 52, the air first passing through suitable filtering means 58, such as frames of spun glass or the like. The blower unit 52 and filtering means 58 are housed within the casing 56. The outlet 5| of the blower unit 52 communicates with the open lower end of the casing 16. As shown in Figure 1, the side walls of the member 26 are longitudinally fluted, so that air may pass through the casing I6, in close contact with the walls of the member 26, to risers 25 leading to the rooms to be heated. Suitable mechanism providing for and controlling the supply of fuel to the burner is shown as generally supported by a foot I35.

The lower end of the outer casing I5 is suitably secured to a base 29,which in this case comprises a support member 2|, generally rectangularly shaped in plan view. The member 2| may be formed of connected bars of angle iron, the bars preferably having a Z cross-section, as best shown in Figure 3. The end portions 22 and 23 of the Z-bar formation extend in a generally upright direction, whereas the intermediate portion 24 extends in a generally horizontal direction.

Straps 29 are secured to the portions 23 of the supporting member 2], in position to span opposite sides of this member. A supporting plate 30 overlies the straps 29, and provides a supporting surface for the foot I35, chamber member 26, and blower unit 52. The end portion 23,- of the Z-bar construction, is adapted to rest on the supporting surface, whereas the end portion 22 provides a flange to which may be secured the lower end of the casing l5 in any suitable manner.

Means are provided to effect adjustment of the base 20, and the air conditioning apparatus carried thereby, with respect to a supporting surface, such as a basement floor. In the embodiment here shown, the intermediate portion 24 of the Z-barformation is provided with a threaded aperture 3| I at spaced-apart places, such as the four corners of the rectangular member 2|, and threaded through each of the apextures3l is a bolt. 21.

The supporting surface shown in Figure 3 is of an uneven nature, having a depression 28. In some instances, whenthe terminal margin of the end portion 23 of the base 20 rests directly on such an uneven surface, the air conditioning apparatus is not steadily supported, and may wobble.-

To prevent such wobbling, the bolts 21 may be so adjusted as to insure proper support base. As seen in Figure 3, the bolt 2! adjacent the recess 28, has been turned so that its end seats in the bottom of the depression 28, thereby obviating any wobbling tendency of the base which might be caused by the unevenness of the basement floor. It will be obvious that the bolts 2'! also may be adjusted so as to effect levelling of the base 20, or to compensate for inclination of the supporting surface, or in some cases, to tilt the base with respect tothe sup-I porting surface.

"The base 20 is of a smaller transverse outer size-than the casing I 5, providing a step between the base and the casing. The heads of the bolts 21 are disposed within the casing l5, whereas-the threaded shanks of the bolts extend through the space formed by the step,and are substantially out of the way and out of sight.

It will be apparent to those skilled in the art that I have accomplished at least the principal object of my invention, and it also will be apparent to those skilled in the art that the embodiment herein described may be variously changed and modified, without departing from the spirit of the invention, and that the invenfor the.

tion is capable of uses and has advantages not herein specifically described; hence it will be appreciated that the herein disclosed embodiment is illustrative only, and that my invention is not limited thereto.

I claim:
